WALTER S. vSTEVENSON, OF PHDILADELPHIA, PENNSYLVANIA.

Letters Patent No. 101,177, dated Mal/rch 22, 1870; antedafted January 5, 1870.

r The Schedule referred to in thse Letters Patent and making part of the ame I, WALTER S. Srnvnlvsos, of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented certain Improvements in Cook-Stoves, oi' which lthe following is a specication.

Nata/rc wml Object 'of7 the Invention. v

My invention consists of a cook-stove, having a depressed hearth-plate, to which is iitted a rotating sitter and a circular vessel for .receiving the ashes, as .Fully described hereafter.

Description of the Accompanying Drawing. lFigure 1 is a vertical section of suicient of a cookstove to illustrate my invention;

Figure 2, a sectional plan on vthe line 1 2, tig. l; andll`igure 3, a vertical section of the sifting apparatus detached from the above.

" Gene/ral,V Description.

A represents the fire-place of a cooking-stove or range;

B, the back ofthe tire-place;l

C, part ofthe fixed front grate;

D,'the bottom plate; and

E, -the hearth-plate.`

The bottom grate D is pivoted, so that it can be vagitated and tilted in the manner clearly indicated in ceptacle G', which, with its contents, may be from time to time removed, thereby avoiding the necessity of repeatedly removing small quantities of .ashes by a shovel or shovel and rake. i

With the depressed hearth-plate is combined a sitter, composed of a perforated plate, G, revolvingr on a cross-bar or bars, a, in the lower portion ofthe hearth-plate, the grate being pivoted to the bar by a pin, b, at a short distance from which the rod H is connected `to the sifting-plat,ethe rod passing through thehearth-plate, and being furnished with a suit-able handleor knob, so that by reciprocating the said rod a vibrating motion may be imparted to the siftingplate, thereby separating the ashes, whichfall into the receptacle G', from the'ci'nders, which remain on the plate and are available as fuel.

' The vessel or-receptacle G' has on its opposite edges slots e e, of the form shown in fig. 3, the slots being so adapted to pins 4on the cylindrical projection of the hearth-plate, that the vessel, after being adj usted .to

theprojection and partially turned, will he secure in its place.

C lam.

The combination, with a stove, of a vdepressed hearth-plate, having an opening and a ange, F, a rot-ating sifter adapted to the said opening, and a detachable'vessel, G', having slots e, adapted to pins on the flange F, as described.

In testimony whereof l have signed my name to this specification in the presence of two subscribing witnesses.
